This is the highest-sovereignty variant of RKP-1 (Full On-Chain). The anchoring mechanics are identical - the difference is that both the cloud infrastructure and the blockchain are EU-operated and EU-governed.
Sovereignty Profile
When to choose this variant: Your regulatory environment, national security classification, or contractual obligations require that no part of the integrity infrastructure - cloud, storage, or blockchain - is subject to non-EU jurisdiction or accessible by non-EU authorities.
What Is EBSI?
EBSI (European Blockchain Services Infrastructure) is the EU’s own blockchain network, operated by the European Commission in collaboration with EU member state governments. It was designed for EU public sector use cases - including the European Digital Identity Wallet (EUDIW), educational credential verification, and government document authenticity.How It Differs from RKP-1 Standard and RKP-1 Enhanced EU
Anchoring Architecture
Regulatory Frameworks Addressed
Use Cases Best Suited to RKP-1 Sovereign EU
National critical infrastructure
Energy, water, transport, and digital infrastructure operators subject to NIS2 with national classification requirements.
EU government and public sector
Public authorities anchoring administrative records, official documents, and regulatory filings under EU law.
EU Digital Identity Wallet workflows
Credential issuers and verifiers participating in the EUDIW ecosystem, where EBSI anchoring is native.
Defence-adjacent and classified environments
Organisations with obligations or preferences against relying on non-EU blockchain networks for integrity proofs.
Availability
RKP-1 Sovereign EU is available on request for organisations with demonstrated sovereignty requirements. Deployment involves:- Dedicated OVH tenancy for API processing and storage
- EBSI network configuration for blockchain anchoring
- EU-law-governed data processing agreement
- Modified API endpoints scoped to the sovereign deployment
